Making Peanut Butter & Jelly Cookies is both enjoyable and simple. Follow these steps for an incredible baking experience:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Mix Peanut Butter and Sugar: In a large bowl, combine the peanut butter and granulated sugar. Mix well until smooth.
3. Add Egg and Vanilla: Beat in the egg and vanilla extract until fully incorporated.
4. Add Baking Soda and Salt: Sprinkle in the baking soda and salt, then mix until well combined.
5. Form Cookie Dough: Using a cookie scoop or tablespoon, portion out the dough and roll it into balls. Roll each ball in extra sugar if desired for a sweet crust.
6. Prepare for Jelly: Place the cookie balls onto the prepared baking sheet, leaving space between each. Press your thumb gently into the center of each ball to create a small indentation.
7. Fill with Jelly: Spoon a small amount of jelly into each indentation. Be careful not to overfill.
8. Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
9. Cool Down: Remove from the oven and allow to cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely.

By following these steps, you’ll have a delicious batch of Peanut Butter & Jelly Cookies in no time!
